Hello everyone. I'm currently riding on a 2014 Fuji Touring Bike (aka the Green Monsta) and am currently saving up for a multiyear around the world tour. I'm hoping to leave mid summer 2016 or beginning of 2017. Anywho, I'm planning on cycling Patagonia as well as eventually several other South American and Southeast Asian countries to start and eventually also India/Nepal. I'm rocking 700c tires and wonder if anyone has any personal experience touring in the developing world on tires that size. I'm mostly wondering if it is better to

A. Buy the strongest/most durable wheels I can find and carry extra spokes/tires/tubes and be prepared to spend money (if anyone has ever done this and could quote how much it cost to have a part fed ex'ed to say, remote Chile it would be awesome) and lots of time to have things shipped to wherever I happen to be in case I have an equipment failure.

or

B. Drop $$$$ on a LHT or Co-Motion Pangea with 26inch wheels.

I'm currently planning on doing option A until my current bike gets stolen or damaged beyond repair.

Thanks everyone for your help and happy holidays!
